Reading Assessment Program Overview: Lexile Framework®

Learn More about the Lexile Framework for Reading

The Lexile Framework® is a Research-Proven System for Measuring Students' Reading Levels and Matching Readers to Text

The Lexile Framework uses a common metric to evaluate both reading ability and text difficulty. By placing both reader and text on the same scale, the Lexile Framework® allows educators to forecast the level of comprehension a student will experience with a particular text, and to evaluate curriculum needs based on each student's ability to comprehend the materials.
